This makes development much easier and faster. In addition, the operating system provides the necessary drivers for hardware peripherals, such as networking and storage.

The working principle of the VL-EPM-15G is based on FPGA technology. FPGA stands for Field-Programmable Gate Array and is a type of integrated circuit (IC) that can be configured by the user to perform specific tasks. An FPGA is composed of many logic elements, such as gates and registers, and a programming mechanism, such as a JTAG interface or a RAM-programmable configuration memory.

The FPGA inside the VL-EPM-15G can be programmed to implement custom logic, such as state machines or data processing algorithms. This allows for the user to tailor the board to their specific application requirements, while providing the power and flexibility of an FPGA architecture. Some common tasks that can be implemented on the FPGA include data acquisition, signal processing, and protocol conversion.

In addition to providing a powerful programmable platform, the VL-EPM-15G also supports development tools such as Xilinx Vivado, Xilinx SDK, and ISE Design Suite. These development tools allow for the rapid creation of custom hardware designs, such as digital filters and hardware accelerators.

In conclusion, the VL-EPM-15G is a powerful single board computer based on Xilinx Zynq-7000 FPGA. It is suitable for a wide range of applications and provides an excellent platform for custom hardware designs. The FPGA provides the power and flexibility of an FPGA architecture, allowing for custom logic implementations for specific applications. Additionally, the board includes operating system, development tools, and numerous peripherals for user convenience.
